Pirelli P ZERO SmarTUBE 80mm
Lightweight and compact - the Pirelli P Zero SmarTUBE
Instead of the standard material for bicycle inner tubes, butyl, the Pirelli P Zero SmarTUBE relies on thermoplastic polyurethane, TPU. This is an advanced plastic that is characterized by elasticity and mechanical strength. The result is a tube that can be up to 70 percent lighter, up to 50 percent more compact and overall more puncture resistant than a comparable tube made of butyl.
The P ZERO SmarTUBE is the ultimate evolution for cyclists who continue to rely on the standard clincher tire setup and want to increase the performance of their road bike by saving weight where it counts: on the outer area of the rotating mass.
Note: TPU is a plastic material that will not stretch back under extreme deformation - unlike butyl, which has shrinkage characteristics. TPU always needs a counterpart - in this case the casing - to remain dimensionally stable. For this reason, the tube should be slightly inflated during installation (maximum 0.3 bar) and then mounted with the tyre.

Crevaison sur route avec un pneu Continental GP5000, chambre à air impossible à réparer sur place ainsi qu'à la maison . Le Kit rustine vendu spécialement pour cette chambre à air n'est pas du tout efficace , la rustine ne tient pas même après plusieurs essais. Donc 25 euros de perdu , cela fait cher le trou... je ne la recommande pas du tout. Ou alors juste pour le gain de poids non négligeable.
Montage problemlos. Halten die Luft meiner Erfahrung nach wesentlich besser (länger) als Turbolitos (bei nahezu identischem Gewicht). Packmaß ist bei TPU natürlich wesentlich geringer als bei Butyl und Latex, da reicht dann eine kleine Satteltasche. Die Preise müssen aber noch sinken.
